摘要：
A liquid ejection head includes a substrate having an energy-generating element for generating energy to be used for ejecting a liquid and a supply port in the form of a through-hole for supplying the liquid to the energy-generating element, and an orifice plate including an ejection orifice for ejecting the liquid. A plurality of the energy-generating elements is arranged in a first direction. The supply port is formed between the plurality of the energy-generating elements in the first direction, and the supply port is formed so as to be adjacent to the energy-generating element in a second direction orthogonal to the first direction.
